304L Pipe
304L pipe is a stainless steel pipe with low carbon content. It is designed to resist rust and corrosion, especially after welding. This pipe is great for use in wet, chemical, or high-heat environments. It’s often used in industries like food processing, water systems, and petrochemicals, where strength and cleanliness are important.
304L Tubing
304L tubing is a stainless steel tube that resists corrosion and is easy to shape and weld. Its smooth surface makes it ideal for transporting liquids or gases, especially in industries that require cleanliness, like pharmaceuticals and food production. It’s a reliable choice for projects needing durability and hygiene.

Heat Treatment
Heat Treatment
Common heat treatment processes of 304L pipe & tubing:
- Normalizing
- Not applicable
- Reason: Not suitable for austenitic stainless steel.
- Annealing
- Temperature: 1010-1120°C (1850-2050°F)
- Process: Restores ductility and removes internal stresses.
- Quenching
- Not recommended
- Reason: Doesn’t improve hardness; may cause warping or cracking.
- Tempering
- Not applicable
- Reason: 304L is not hardened by heat treatment.
For both 304L pipe and tubing, annealing is the only applicable heat treatment, while normalizing, quenching, and tempering is either not applicable or not recommended due to the nature of austenitic stainless steel.
